在没有 WINRM 的情况下将文件从本地服务器复制到远程服务器 [英] copy a file from a local server to remote server without WINRM

问题描述

我想在没有 WINRM 的情况下将文件从本地服务器复制到远程服务器.远程服务器已获得凭据，但不在本地网络或本地服务器的本地域中.请问您有解决办法吗?

I want to copy a file from my local server to a remote server without WINRM.The remote server has got credentials and is not in the local network or the local domain of my local server. Do you have a solution ,please?

I have this error:
MethodInvocationException: D:\powershell\ip.ps1:23:1
Line |
  23 |  $WebClient.DownloadFile($Source, $Dest)
     |  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
     | Exception calling "DownloadFile" with "2" argument(s): "An exception occurred during a WebClient request."


Here is my code:


$Source = "C:\test10\test10.txt"
$Dest   = "\\public_ipadress_server\C:\test11\test10.txt"
$Username = "administrator"
$Password= convertto-securestring -AsPlainText -Force -String password
$MyIP = (Invoke-WebRequest -uri "http://ifconfig.me/ip").Content
$MyIP | Out-File $Source 
$WebClient = New-Object System.Net.WebClient
$WebClient.Credentials = New-Object System.Net.NetworkCredential($Username, $Password)

$WebClient.DownloadFile($Source, $Dest)

推荐答案

是否可以使用标准的 UNC 网络副本?我会考虑将驱动器映射到远程 PC 上的共享.net use 命令将允许您执行此操作，输入远程计算机的凭据.然后您可以通过映射的驱动器复制文件.我还添加了一些代码，以更安全的方式提供凭据.以明文形式存储密码不是很好的做法，这似乎是您正在做的.

Would it be possible to use standard UNC network copy? I would consider mapping a drive to a share on your remote PC. net use command will allow you to do this entering credentials for the remote computer. Then you can copy the file over via the mapped drive. I also added some code for providing the credentials in a more secure way. It is not very good practice to store passwords in clear text which it appears you may be doing.

$source = "C:\test10\test10.txt"
$desiredMappedDrive = "J"
$desiredMappedDrivePath = "\\public_ipadress_server\C$" # Map to administrative C: drive share requires administrator credentials)
$destination   = "${desiredMappedDrive}:\test11\test10.txt"


$passwordFile = "C:\temp\encryptedCred"
if (-not (Test-Path $passwordFile) ) {
    $cred = Get-Credential
 
} else {
    $fileContents = Get-Content $passwordFile
    $userEncryptedString = $fileContents[0]
    $passEncryptedString = $fileContents[1]
    $userSecureString = $userEncryptedString | ConvertTo-SecureString
    $passSecureString = $passEncryptedString | ConvertTo-SecureString
    # convert secure string back to text
    $userString = [System.Runtime.InteropServices.Marshal]::PtrToStringAuto( [System.Runtime.InteropServices.Marshal]::SecureStringToBSTR($userSecureString) ) 
    $cred = [pscredential]::new($userString, $passSecureString)
}

if ($cred) {
    $response = net use ${desiredMappedDrive}: $desiredMappedDrivePath /USER:$($cred.UserName) $($cred.GetNetworkCredential().Password)
    $response

    if ($response -match "command completed successfully") {
        $cred.UserName | ConvertTo-SecureString -AsPlainText -Force | ConvertFrom-SecureString | Out-File $passwordFile
        $cred.Password |ConvertFrom-SecureString | Out-File -Append $passwordFile
        Write-Host "Credentials have been saved to $passwordFile.  While file exists you will not be asked to enter credentials for future script executions"
    }


    Copy-Item $source -Destination $destination
}
